A 54-year-old Manitoba man is dead after he left his car in a ditch during a winter storm.

St. Pierre Jolys RCMP said the man was found unconscious on Road 45N, off of Provincial Road 210, about four kilometres west of Landmark early Monday. Efforts to rescusitate him were unsuccessful.

Police said it appeared the man's vehicle ended up in the ditch and the man tried to walk from the area. His body was found about 50 metres from the vehicle.

RCMP are now investigating his death but said foul play is not suspected.

Driving conditions were poor throughout southern Manitoba on Monday with whiteout conditions on the Trans-Canada Highway between Headingley and MacGregor.

Black ice, blowing snow and packed drifts made driving dangerous on most roads across the south. The Trans-Canada between Headingley and Portage la Prairie, along with Highway 75 between Winnipeg and the US border, were closed for much of the day. The Trans-Canada Highway was re-opened early Monday evening.

Road conditions

The RCMP responded to numerous collisions Monday, mainly due to poor visibility and bad road conditions.

Officers were on scene in St. Francois Xavier in the morning, after a 10-car pileup that included several semi-trucks. No one was seriously injured in the crash.

RCMP said three semi-trailer trucks also collided just west of Provincial Road 332 on Highway 1.

In addition, two semis rammed barricades in Headingley. Flying debris damaged a police cruiser but no officers were hurt.

In Winnipeg and surrounding area, the snow tapered off in the morning but high winds impaired visibility through much of the day.

City officials deployed their snow-clearing on major routes and sidewalk clearing was expected to begin Tuesday morning.

Truckers stranded in Headingley

Dozens of truckers were forced to wait out the storm in Headingley.

Trucker Marc LaFond said conditions were terrible and semi-drivers risk being pushed right off the road.

"You can’t see the car in front of you," said 53-year-old LaFond.

"You got no control, so you are better off to park it."

They haven’t received any word on when the highway will be reopened.

Blowing snow, blizzard warnings

Environment Canada earlier issued a blowing snow warning for a wide swath of southern Manitoba, from Portage la Prairie to the Ontario border and from the Interlake Region to the United States border.

Winds gusted up to 70 km/h with the worst conditions in the southern Red River Valley. About 10 centimetres of snow is expected to fall near the Manitoba–U.S. border with up to 15 centimetres in the southeast region of the province.

Power outages

Hundreds of people in and outside of Winnipeg were dealing with power outages on Monday morning.

A pole fire near Lagimodiere Boulevard and Maginot Street caused on outage in Winnipeg's Windsor Park area, while another pole fire on Queen Street affected some customers in the St. James area.

A blown transformer at Elizabeth Road had shut down service to more areas and crews also dealt with an outage in Ile-Des-Chenes.
